💻 The RAM shortage could last years Demand for memory chips has surged in recent years, driven by rapid growth in AI technologies and data-intensive applications. This has put increasing pressure on global supply chains, especially for RAM, which is essential for both data centers and everyday devices. A global RAM shortage is expected to continue for several years, with supply projected to meet only about 60% of demand by the end of 2027. Major manufacturers are working to expand production, but most new facilities won’t be ready until 2027 or later. While output needs to grow by roughly 12% annually to keep up, current plans fall short at around 7.5%. Much of the new capacity will focus on high-bandwidth memory used in AI data centers, leaving less production for standard DRAM in consumer devices. This imbalance is already driving up prices for products like smartphones, laptops, and gaming devices, and relief may remain limited even as new factories come online. ⛓ More information... #news
